STTS75 - Digital Temperature Sensor and Thermal Watchdog

The STTS75 is a high-precision CMOS (digital) temperature sensor IC with a delta-sigma ADC and an I2C-compatible serial digital interface. It is targeted for general applications such as personal computers, system thermal management, electronics equipment, and industrial controllers, and is packaged in the industry standard 8-lead MSOP (TSSOP) and SO packages.

The device contains a band gap temperature sensor and programmable 9-to 12-bit ADC which monitor and digitize the temperature to a resolution up to 0.0625°C. The STTS75 is typically accurate to (±3°C - max) over the full temperature measurement range of –55°C to 125°C with ±2°C accuracy in the –25°C to +100°C range. At power-up, the STTS75 defaults to 9-bit resolution for software compatibility with the STLM75.

STTS75 is specified for operating at supply voltages from 2.7 V to 5.5 V. Operating at 3.3 V, the supply current is typically (75 μA).

The on-board delta sigma ADC converts the measured temperature to a digital value that is calibrated in °C; for Fahrenheit applications a lookup table or conversion routine is required. The STTS75 is factory-calibrated and requires no external components to measure temperature.

The STTS75DS2F is a MSOP8 Digital Temperature Sensor and Thermal Watchdog that comes in a 1000 piece reel.
